My hosting company is not being very supportive. Can someone tell me the best step by step method for moving our forums from ourdomain/forums to a subdomain forums.ourdomain.com ?
From what he wants to do, he doesn't need to move files, they are already in directory. He just needs to setup subdomain to that directory, call it as he like it and setup .htaccess rule for redirection, so people (and the rest of internet, of course) can find it and use it. And, of course, XF ACP thingy.
There's nothing to prevent you from logging into the admin cp no matter what the url is in the settings. Put "admin.php" in the URL and Xenforo doesn't care about the settings, it will take you straight to the admin panel. They probably do this specifically to keep you from being locked out.
